Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment, and in particular to an integrated photovoltaic device for water purification and cooling. Background Art

[0002] The low-carbon development of the power industry faces severe challenges. Building a new power system with clean energy as the main body is an important measure to achieve the "dual carbon" goal; surface photovoltaics, as a clean energy, has been widely used on the surface of coal mining subsidence ponds in recent years.

[0003] Coal mining has formed a large number of coal mining subsidence waterlogging areas. The development of water surface photovoltaic power stations has provided new technologies for the treatment of coal mining subsidence waterlogging areas. It can not only effectively utilize the idle and abandoned water resources in coal mining subsidence waterlogging areas, but also remove the constraints of land occupation factors in the development of photovoltaic projects and broaden the application of photovoltaic power generation. At the same time, it can improve power generation efficiency, reduce free surface evaporation of water bodies, reduce carbon footprint and generate electricity, thereby maximizing comprehensive benefits.

[0004] However, water surface photovoltaic also has some impact on the water quality of coal mining subsidence waterlogging areas. Water surface photovoltaic can change the wind direction on the surface of the water body, reduce the interaction between wind and water body, reduce the contact area between water body and air, and reduce the dissolved oxygen content in water. Weakening the light intensity on the surface of the water body affects the growth of aquatic plants, reduces photosynthesis and reduces the production of oxygen in water. The growth of aquatic plants is restricted, which also affects their absorption and utilization of nitrogen and phosphorus in the water body. On the other hand, under the comprehensive utilization of aquaculture water surface, building photovoltaic power stations on the water surface to achieve "fish-light complementarity" is becoming a major trend, which poses a challenge to how to scientifically coordinate the power generation utilization of the water surface and the aquaculture pollution purification function of the water body. There are livestock such as chickens and ducks on the shore of the coal mining subsidence waterlogging area, and the aquaculture wastewater generated is directly discharged into the water body in the waterlogging area, which also has an impact on its water quality that cannot be ignored. The front of the photovoltaic panel is the surface directly exposed to sunlight, while the back is the surface that contacts the bracket or other supports. These objects will absorb and conduct the heat from the front of the photovoltaic panel, and there is often not enough air circulation on the back, making it difficult to dissipate heat. When the components are overheated, the increase in temperature will affect the current and voltage, which means that the working efficiency of the photovoltaic panel will be affected to a certain extent.
